Table 2 The LT50 values of juvenile grass carp subjected to different levels of TDG-supersaturated water after chronic exposure (multiple exposures)

From: Effect of total dissolved gas supersaturation on the tolerance of grass carp (Ctenopharyngodon idellus)

Exposure conditionTDG levels (%)LT50
Multiple exposures1405.34 ± 0.42a

  1. The data are described as the mean ± SD (n = 2). Letters following the LT50 values indicate the results from a post hoc multiple comparison test between varied TDG levels. Lower-case letters apply to the effects of TDG on juvenile grass carp. Values that do not share a common letter are significantly different
  2. – indicates that the LT50 value of juvenile grass carp at the 125% TDG level was not calculated (more than half of the individuals were still alive at the end of the experiment)
